This is certainly one of the "screening" items among hiring airlines that is totally INconsistent through the industry. Some airlines don't particularly care; others use it as a screening factor.
Personally, I think flying "glass" is MUCH easier for a "good" pilot becasue there is more information available. However, that pilot stays "good" by using the information intelligently.
Finally, the analog-to-glass transition is MUCH easier than the other way around. Once you develop your good airmanship on the steam gauges, you shouldn't lose it because a magenta line appears in front of you.
